Problems solved by technology

[0003] In related technologies, when the uplink shared channel of the terminal device is enabled with the UL skipping function, if the time domain resource of the uplink control channel (such as a physical uplink control channel (PUCCH)) and the dynamic scheduling There is a resource conflict in the time domain resources of the uplink shared channel. Since PUSCH may have no data to send, the MAC layer generates PDUs based on whether there is data, and cannot generate PDUs based on whether there is UCI to be multiplexed.

[0119] When the UE enables the PUSCH UL skipping function, if the UE receives one or more UL grants, at least one PUSCH on one or more carriers is scheduled, and the UE receives one or more DL grants, one or more When there are multiple PUCCHs carrying UCI, the UE can determine the transmission of UCI according to the following steps:

[0120] Step 11: Decode DL grant and / or UL grant.

[0121] Step 12: If there are multiple PUCCHs, the PHY layer determines the resource of the target PUCCH bearing UCI according to the multiplexing rule of UCI on PUCCH.

[0122] Step 13: If the target PUCCH resource conflicts with at least one PUSCH on the above-mentioned one or more carriers, the PHY layer determines the target PUSCH resource for carrying UCI in at least one PUSCH according to the UCI on PUSCH multiplexing priority .

[0123] Step 14: The PHY layer notifies the MAC layer of UCI multiplexing information (that is, the content in step 13), and the MAC generates a MAC PDU accordi...

[0139] When the UE enables the PUSCH UL skipping function, if the UE receives one or more UL grants, at least one PUSCH on one or more carriers is scheduled, and the UE receives one or more DL grants, one or more For multiple PUCCHs carrying UCI, the UE determines the transmission of UCI according to the following steps:

[0140] Step 31: Decode DL grant and / or UL grant.

[0141] Step 32: The PHY layer notifies the MAC layer after step 31 that the one or more PUCCHs carrying UCI conflict with at least one PUSCH on the one or more carriers.

Abstract

The invention discloses an uplink transmission method and device and equipment, belongs to the technical field of communication, and aims to realize that an MAC layer can generate a PDU based on whether UCI needs to be multiplexed or not. The method comprises the following steps: when terminal equipment enables an uplink transmission skipping function, if a time domain resource of at least one uplink shared channel is overlapped with a time domain resource of at least one uplink control channel, processing the time domain resource of at least one uplink shared channel on an MAC layer according to any one of the following processing modes, generating an MAC PDU (Media Access Control Protocol Data Unit): if the MAC layer knows that the time domain resource of the uplink shared channel is overlapped with the time domain resource of the uplink control channel, generating the MAC PDU; generating an MAC PDU (Media Access Control Protocol Data Unit) according to multiplexing information notified to the MAC layer by the physical layer; wherein the at least one uplink control channel carries at least one piece of uplink control information.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to an uplink transmission method, device and equipment. Background technique [0002] When the uplink shared channel (for example, physical uplink shared channel (PUSCH)) of the terminal device enables the function of uplink transmission skipping (UL skipping), and there is no data to be transmitted in the data memory of the terminal device, Even if the base station schedules the user for data transmission, the UL skipping function will allow the user to ignore the scheduling of the base station and not perform uplink transmission. [0003] In related technologies, when the uplink shared channel of the terminal device is enabled with the UL skipping function, if the time domain resource of the uplink control channel (such as a physical uplink control channel (PUCCH)) and the dynamic scheduling There is a resource conflict in the time domain resources of ...
